Application iiled February 15, 1900. Serial No. 5,239. (No model.)

To all whom, it may concern:

f Beit known that I, MERRITT C. CONWAY, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Sewers, of which the following, taken in connection with the accompanying drawing, is a full, clear, and exact description. V

This invention relates to the construction of sewers, and particularly to that` class in which sections or tiles are employed, which sections are provided with means for interlocking the same.

The main object of the invention is to produce a sewer which shall ,be strong, rigid, and durable, can be quickly constructed, and at the same time shall be inexpensive.

To that end the invention'consists, essentially, of a sewer comprising a base composed of two side sections and a central section interlocked with said sidesections and extending above the same, the walls comprising interlocking sections, the lowermost wallsection resting partly upon the central seotion and partly upon the side sections and interlocked therewith, crown sections interlocked with the uppermost wall-sections, andl two side sections A' A and the central seo.

tion A2. The side sections are provided with iiat bottoms and have their inner sides converging downwardly and each formed with a longitudinal outwardly-inclined shoulder a, and the tops of said sections slope inwardly, as shown at a. The central section A2 has its sides converging likewise and formed with corresponding shoulders o? a2, which are interlocked'with the shoulders a o. lSaid eentral section extends above the side sections A A and is formed with upwardly-diverging longitudinal tongues a3 ots, which project over the tops of said side sections. The bottom of the central section is preferably slightly above the bottoms of the side sections, and the top of the said section is depressed or concave 'lhe side base-sections A' A' are formed tion is formed with webs a5 a5, which serve to strengthen the same.

B B represent the Wall-sections, the lowermost of which are formed at theirlower sides with longitudinal inwardly-sloping grooves b b, which receive the aforesaid tongues a3 cts on the central section, and also formed with likewise-sloping longitudinal tongues b' b', which engage corresponding grooves Z22 4b2 between the tongues a3 as and tops of the side sections, whereby said wall sections rest partly upon the said central section and partly upon the side sections and are interlocked therewith. The upper sides of the lowermost wall-sections B B are formed with inwardly-sloping longitudinal tongues b3 b3 and grooves b4 b, which are interlocked with corresponding grooves c c and tongues c c', formed at the lower sides of` the upper wallsectionsB B. The upper sides of the uppermost wall sections are formed with like tongues 02,02 and grooves c3 c3, which are interlocked with corresponding grooves d d and tongues d d', formed at the lower sides of the crown-sections D D, and the upper sides of said crown-sections are formed with longitudinal acute-angled shoulders d2 d2, which are interlocked with like shoulders d3 d3, formed on the sides of the key-section D.

It will then be seen that by forming the i11- terlocking tongues and grooves in the manner described the sections are caused to be drawn inwardly, and thus become wedged together, thereby producing a very strong and rigid construction.

The wall-sections B B, the crown-sections D D, and key-section D' are formed with strengthening-webs e e' e2, respectively.

It is to be understood that the various joints throughout the construction are to be left with sufficient space to admit of cement in the usual manner. Furthermore, it will be seen that the principle employed for interlocking IOO l.
